Hard Bounce processed as Soft Bounce


Dear guys!
Lately I have another problem that is causing me a bit of a problem with IP / domain reputation and this is due to some bounces being classified as Soft instead of being classified as Hard!

The error is as follows:
"smtp; 554 30 Sorry, your message to example@ymail.com cannot be delivered. This mailbox is disabled (554.30)."

Strangely I applied the rules in the rules-custom-override.php file as suggested in this thread https://forum.mailwizz.com/threads/bounce-rules.5742/ but the problem turns out to be the same, why?

I am attaching my rules-custom-override.php file

Thanks in advance

and if we wanted to make it HARD Bounce what should we do?
These are the rules the above string hit, in this order:
Matched rules:
    [0] => Array
            [/mail(box|folder)(\s+)?(is|full|quota|size)(\s+)?(full|usage|limit)?(\s+)?(exceeded)?/i] => soft

    [1] => Array
            [/is disabled/i] => soft

    [2] => Array
            [/is disabled/i] => soft

    [3] => Array
            [/(?:alias|account|recipient|address|email|mailbox|user).*(?:disabled|discontinued)/i] => hard

So if you remove the first 3 rules from the soft bounces rules(yes i know, duplicate rule, i have fixed it :p), it will hit the hard bounces one.
We don't recommend doing this, but if you are sure about it, go for it.
